CompleteWizardStep bypass confirmation

I have a create account page that uses the CreateUserWizard. Currently when the user clicks the "Creat User" button they receive a confirmation message that says the account has been successfully created. I'd like to bypass this confirmation and take them directly to another page. 
In the CreateUserWizard I've set LoginCreatedUser="true" and ContinueDestinationPageUrl="~/mypage.aspx", obviously this isn't the way to bypass that confirmation message. How can I send the user to "~/mypage.aspx" when they click the "Create User" button.
